It's a beautiful place and the food is amazing.

I personally love photo arts and this gallery puts on some amazing exhibitions by the best artists, such as Vivane Sassen and Gregory Crewdson. The Gallerys’ six-storey space is located right by Oxford Street, so if you are doing some shopping in London, you might as well stop by this gallery. The upper floors consist of two new galleries, while the ground floor hosts a nice café/restaurant. Together with the print sales, the bookstore occupies the basement of the building. I can spend hours just looking at the books, how it is designed, bound, as well as the prints for sale. You can buy all kinds of film; medium format to polaroid film at the store. After some hours at this gallery you just want to go home and start making some photography! 

An obvious choice but no 'best of London' list is complete without the Barbican

Lovely, open space close to Highbury and Islington with tennis courts, netball courts, kids' playground and Parkrun on a Saturday morning at 9am!  

One of a trillion reasons Brixton is the best.
